Well polished game with a fun gameplay loop. The music is just a touch loud and repetitive. It's tough to balance a tower defense game, and on the second level I had purchased all of the troop slots and just watched myself win for 5 or 6 rounds. Overall fun and polished gameplay that worked very well. I don't know how well thief fits into this, other than the troops are taking your flag which would be soldiers, not really thieves.
Overall fun game with a lot of polish for such a quick jam.
